Geniemat FF03NP-S 3mm Acoustic Underlay Sheet - 2.6m²
Geniemat FF03NP-S 3mm is a low-profile acoustic underlay sheet designed to reduce impact sound transmission through floor structures. It is commonly used directly below screed or gypsum concrete in residential, commercial and multi-occupancy buildings.
Each sheet measures 1.22m x 2.13m and covers approximately 2.6m², making it easy to calculate quantities for apartments, flats, student accommodation, hotels, offices and other acoustic flooring projects.
Made from robust recycled rubber material, Geniemat FF03NP-S creates a resilient separation layer between the structural floor and the screed. This helps reduce footfall noise, vibration transfer and structure-borne sound movement through the floor.
For best performance, it should be installed as part of a complete acoustic floor build-up with correct joint treatment, perimeter isolation and control of flanking noise paths.

Installation notes
Install Geniemat FF03NP-S over a clean, dry and level structural floor. Sheets should be laid tightly together, with joints treated according to the project specification.
Use suitable perimeter isolation around walls, columns, service penetrations and fixed structures. This prevents the screed from forming a rigid bridge into the surrounding structure and helps reduce flanking noise.
Do not puncture or mechanically fix through the acoustic layer unless allowed by the full floor system specification.
FAQ
What is Geniemat FF03NP-S used for?
Geniemat FF03NP-S is used below screed or gypsum concrete to reduce impact noise through floor structures.
How thick is it?
It is a 3mm nominal acoustic sheet.
How much does one sheet cover?
Each sheet covers approximately 2.6m².
Can it be used in flats and apartments?
Yes. It is suitable for flats, apartments, student accommodation, hotels and commercial acoustic flooring projects.
Does it need perimeter isolation?
Yes. Perimeter isolation is strongly recommended to reduce flanking noise and prevent the screed from touching surrounding walls or fixed structures.
